I did reprocessed this nebula since my skills are much better now, than two years ago.

3D-studies from this object can be found from previous posts.

Image is in HST-palette, (HST=Hubble Space Telescope)

from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.

An older version of processing and technical details can be found here:

Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.

Distance is about 10.000 light years. Image is about 30' wide and covers about 100 light years.

This is not too commonly imaged target due the lowish surface brightness and the proximity of two eye catchers, IC 405 and IC 410. This image was one of the most difficult one to process due the very weak signal. There was some very dim O-III emission in the target, it can be seen as a Blue.

Please, let the images load for few seconds to see them animated!

NOTE. All the stars have been removed due the amount of artifacts. The actual nebula can be seen better now.

I will shoot more lights for this object later, including O-III and S-II data.

I did reprocessed this nebula since my skills are much better now, than two years ago.

All the exposures I have taken for this object are used. Total exposure time is now about 20h together.

Two camera lenses was used to capture the data, a Tokina AT 300mm f2.8 and a Canon EF 200mm f1.8, both lenses was used at full aperture.

NGC 1499, the "California Nebula" locates in constellation Perseus. Distance is about 1000 light years.

The nebula covers about 2,5 degrees of sky.

Narrowband data was used for Star colors this time, mixture of channels was the same as in first "natural" color composition image here.

There is a formation at Seven a clock, kind of half circle, it might be an old uncategorized planetary nebula?
